"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

"I did some self diagnosing on my central air unit that stopped cooling. I called up Luke and we agreed it was a capacitor issue. He was out with the part, and we were back up and running with barely a drop of sweat. Highly recommended!!"

Air Conditioning questions, answered by experts

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.
